1 A ngle Flo w C ontrols A ngle Flo w Control valves are designed to provide accurate flo w control in a compact, labor saving package. Features like built in push-in fittings, pre-applied thread sealant, convenient s w ivel design and unique needle design all add up to a package that will save time, money and energy w hen accurate control is needed on pneumatic actuators. Choice of built in Series A Q push-in fittings or NPT F connections. Pre-applied T eflon based thread sealant. Recessed scre w driver adjustment or optional knurled aluminum knob. Convenient s wivel feature for ease of tubing alignment. 5 PSI cracking pressure.

OPTIO NS: Electroless Nickel Plated Stem iton Seals BSPT & Metric O D Tube Connections Knurled A luminum Knob w ith Locknut Flo-Set Control alves Flo-Set flo w controls are an effective and accurate means of controlling the speed of pneumatic cylinders. They can easily be mounted inline any w here in your system. A controlled setting of the exhaust port of the cylinder allo w s a set back pressure to smoothly control piston velocity. They are recommended for all pneumatic applications to 150 PSI. Easily mounted for inline applications. A nodized aluminum for corrosion protection. Knurled sleeve for non-slip adjustment. Precision fit so vibration will not change adjusted setting. Excellent controlled flo w and high free flo w. For sizes 1/4, 3/8, 1/2 and 3/4 NPT. 1 9

2 In-Line Flo w Controls, Needle & Check alves The Alkon Series J Flo w Control, Needle and Check alves offer substantially higher flo w than any other comparable valve in their size or pressure range. A lkon pioneered the t w o taper needle and the in-line flo w path designs to provide the highest flo w coupled w ith the most sensitive metering from full open to full closed. A. A luminum control knob permits adjustment of flo w w ith valve under pressure. B. Locking set scre w on control knob. C. Brass retainer acts as a positive stop for needle travel. D. Buna-N seal standard ( iton seal available) onepiece back-up ring to prevent extrusion. E. Heat treated, ground and polished stainless steel needle. F. O ne-piece, high tensile brass forged body. G. Four stage needle provides the most sensitive flo w metering from full closed to full open. H. Large unobstructed orifices. I. Stainless steel ball acts against a lapped seat to provide best sealing. J. The stainless steel cage acts as a spring support ball guide and ball stop. The spring is stainless steel wire. K. In-line check valve has an orifice larger than the nominal pipe size. Lo w pressure differential, no chatter and lo w friction loss.
